Easy health:
To get a health kit, melee a health station.

Easy money:
To easily gain money, go to an area with a working slot machine. For example, in the Siren Alley level inside the Mermaids Lounge, go upstairs into the room on the right side of the balcony that contains the slot machines. As you enter the room, turn left, and play the right-hand machine of the two that are facing you. Save the game before you start, and resave it every time your total money increases above where you started. If the machine does not payout after about a dozen turns, reload your saved game. It is possible to max out your wallet in around ten minutes. Repeat as desired.

Easy Security research:
Find a hackable vending or health machine near a Bot Shutdown Panel. Hack the machine, and stop the pointer on the red to activate the alarm, thus triggering the Security Bots to come after you. Once you see them, quickly take a picture of one of them with the camera, then use the Bot Shutdown Panel to shut them down. The disabled bot will still be highlighted by the research camera, allowing you to research Security easily.

Easy XP in Multiplayer mode:
To easily gain XP in Multiplayer mode, have a friend join your game while it is in progress on any team-based game, putting him or her on the other team. Find a turret anywhere in the map, and make sure there is nobody around. You and your friend can hack the turret back and forth for 10 XP per hack. Repeat as desired.

Alternate endings:
Unlock the following alternate endings by performing the corresponding tasks:

Good ending #1 – Save all Little Sisters you adopt, and spare Grace Holloway, Stanley Poole, or Gilbert Alexander.

Good ending #2 – Save all Little Sisters you adopt, and kill Grace Holloway, Stanley Poole, and Gilbert Alexander.

Standard ending #1 – Save at least one Little Sister, and harvest at least one Little Sister. Choose to die at the end, and spare Grace Holloway, Stanley Poole, and Gilbert Alexander.

Standard ending #2 – Save at least one Little Sister, and harvest at least one Little Sister. Choose to die at the end, and kill Grace Holloway, Stanley Poole, or Gilbert Alexander.

Bad ending #1 – Save at least one Little Sister, and harvest at least one Little Sister. Choose to live at the end, and spare Grace Holloway, Stanley Poole, and Gilbert Alexander. Alternately, harvest all Little Sisters you adopt, and spare Grace Holloway, Stanley Poole, and Gilbert Alexander.

Bad ending #2 – Save at least one Little Sister, and harvest at least one Little Sister. Choose to live at the end, and kill Grace Holloway, Stanley Poole, or Gilbert Alexander. Alternately, harvest all Little Sisters you adopt, and kill Grace Holloway, Stanley Poole, or Gilbert Alexander.

Free Telekinesis:
To pull normal items toward you with Telekinesis and without using any Eve, do the following. Eve is only used when you release the button to throw an item with Telekinesis. Use Telekinesis to pull items such as ammunition or first aid kits toward you to collect without wasting any of your Eve. If you take an item you are already maxed out of, you will either be stuck holding it with Telekinesis or have to release the button to throw it and use some Eve. However, if you display the Plasmid wheel and select another Plasmid attack, you can release the button to drop the item without Telekinesis automatically throwing it. Thus, you will not use any Eve by dropping an item you cannot carry. This can also be used when pulling electrified trip wires out of walls. To do this, pull the item toward you with Telekinesis, and without releasing the trigger, display the Plasmid wheel to select another plasmid. When you close the Plasmid wheel and release the trigger, you will drop the item.

When bringing an item to you that you do not want to throw, and therefore keep from having to use your EVE, press Square to drop the object or press X to take the item if it can go into your inventory.

How to defeat Rumblers:
To easily defeat Rumblers, use Telekinesis to grab the rockets it fires and throw them back at it.

Hacking for Loot:
When you hack a vending machine, stop the needle in the blue section for free ammo or a free eve. Hack a health station using the same strategy to receive a first-aid kit.

Buddy Bots:
When security bots appear after an alarm is triggered, hack them and they will stick around and fight on your side. To easily hack them, stun them with an electric attack first.

Power To The People weapon upgrade station locations:

Power To The People weapon upgrade stations can be found at the following locations:

1. Ryan Amusements – Going to get the ticket.
2. Ryan Amusements – After the family display, through the door.
3. Pauper’s Drop – From Journal 039, go out the door, down the stairs.
4. Pauper’s Drop – In the back of skid row, in the limbo room. It is behind the stage
5. Pauper’s Drop – After breaking into the hotel, when you are going through the halls, you will go through a hole. To the left is a blue sheet. To the right is the station.
6. Siren Alley – In Mermaid Lounge, go upstairs, and hack the gate. Then, drop through a hole in the floor.
7. Siren Alley – Just before Pump Station 5.
8. Dionysus Park – Behind the door; combination is 1080.
9. Dionysus Park – On the path to the train.
10. Fontaine Futuristics – After you destroy the flying Gil bot, you can enter where you gain access to the laboratory.

12. Persephone Outer – On your left.
13. Inner Persephone – After you gain access to Sinclair, look back in the room.
14. Inner Persephone – Just after Ward B in the room with the rocket turret.

How to defeat Big Sisters:
Before you fight the second Big Sister (if you are harvesting ADAM but saving the girls), you will get an Enrage Plasmid. There are two bodies to scrounge ADAM from. One is more easily securable, which has a security camera, a rocket launcher bot, and a large puddle of water in this area. The Big Daddy comes back multiple times. If you drop off the little girl in her hole near here, you can wait for the Big Sister to show up. Then, enrage the Big Daddy so that he will take on and kill the Big Sister. Your only concern will be Splicers and the Big Daddy after he is done with the Big Sister.
